-5 Claims.

The present invention relates to the manufacture of heavy sheet metal containers and has particular reference to 'areinforced end construction for such containers.

Sheet metal containers used for storing and shipping white lead or similar heavy materials are usually made in sizes to contain 25. 50 or 100 pounds of these heavy products. In transportation these heavy containers are roughly handled and are frequently dropped and thrown around and because of their great weight the ends and especially the bottoms of these containers are bent out of shape and sometimes caused to leak unless suitable reinforcing means are provided. In order to strengthen such containers for this rough handling the present invention contemplates the provision of a reinforced bottom construction preferably flared outwardly to substantially the same outer diameter as the outer diameter of the top closure of the container,

thereby enabling the container to be rolled on its side in a straight line instead of being thrown around.

' An object of the present invention is therefore the provision of a container having an enlarged reinforced bottom construction which protects the container against deformation and leaks.

Another object of the invention is the provision ofa container having such areinforced bottom construction which flares outwardly to substantially the same outer diameter as the outer diameter of its top closure providing two spaced rolling surfaces which enable the container to be rolled on its side in a straight line.

A further object is the provision of a container having a straight body wall and wide open mouth so that it may be readily and completely emptied of its contents without waste and in tilting it may be readily grasped by its enlarged and flaring bottom.

Numerous other objects and advantages of the invention will be apparent as it is better under-' stood from the following description, which, taken in connection with the accompanying drawing, discloses a preferred embodiment thereof.

Referring to the drawin Figure 1 is a perspective view of a closed container embodying the present invention;

Fig. 2 is an enlarged vertical sectional view taken substantially along the line 2-2 in Fig. 1; and

Fig. 3 is a sectional view similar to the lower part of Fig. 2 illustrating the body and bottom.

end before they are united together.

As a preferred embodiment of the invention the drawing illustrates a container having a straight annular body wall II. The upper edge of this body wall II is preferably rolled outwardly over a stiifeningwire 12 (Fig. 2) in a curl l3 providing a wide open, unobstructed mouth for the upper end of the container.

This end of the container may be closed preferably by a. detachable cover It utilizing the curl I3 as a cover seat. The cover [4 preferably fits within the container mouth and for this pur pose is provided with a countersunk central recess 45 having a vertical peripheral wall l6 engaging the interior surface of the body wall H adjacent the curl l3. Vertical wall I5 merges into a curved wall H which terminates in a vertical depending wall I. These walls form an inverted U-shaped annulus which overlies the curl 13 when the cover is in .place and which is adapted to hold an annular gasket 19 for engagement with the cover seat I3. When in closed position the cover is clamped on its seat l3 by a series of clamping lugs 2| formed as extensions of the vertical wall l8 and bent under the curl [3 to securely lock the cover in place. I The bottom end of the container is partially reinforced by an outwardly flared and shaped marginal zone formed in the body wall II. In order to provide this reinforcement, the material of the bodys marginal zone is bent outwardly and downwardly in a sloping straight wall annular shoulder 25. The wall 25 mexges into short vertical straight wall 26 which term? in an external flange 21 (Fig. 3). This end of the container is closed gui ar a countersunk end closure 28 fitting within the shaped marginal zone of the body wall and having a formed peripheral wall for cooperating with the inclined body wa1l'25 to provide the full reinforcement of the container bottom. This closure 28 is formed with a dome-shaped central panel 29 which merges into a sloping straight wall 3|. I

This wall extends parallel with and tightly hugs and supports the inclined body wall 25 when 1 the end closure isin place. Wall 3| merges into a short vertical wall 32 which is parallel with and which rigidly supports the body wall 26 at such a time. The wall 32 terminates in a flange 33. This flange 33 is folded and interlocked with the body flange 21 to form a tight seam or .joint 34 (Fig. 2) which includes the vertical walls 26, 32 1 It will be seen that an exceptionally strong end or bottom construction is obtained by the body and end parts 26, 32 being held tightly together in the joint or seam 34 and the walls 25, 1|, rigidly braced by the dome 29, which mutually cooperate, support and reinforce each other.

The outside diameter of the joint 34 is substantially the same as the outside diameter of the cover wall l8, enabling the container to roll in a straight line when it is laid on its side and when supported on these two surfaces.

It is thought that the invention and many of I its attendant advantages will be understood from the foregoing description, and it will be apparent that various changes may be made in the form, construction and arrangement of the parts without departing from the spirit and scope of the invention or sacrificing all of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

We claim:

1. In a shipping container for heavy substances the combination of a cylindrical body, a bottom seamed thereto, a stiffening wire enclosed within the outwardly bent top margin of said body, a detachable cover flttingwithin the top of the body and partially enclosing the top margin of said body and bent to engage below the wire-enclosing part of the body, said bottom being elevated above the bottom margin of the container, the outer portions of the body and bottom being united in a double seam, intermediate portions of the body and bottom being outwardly flared to constitute with said bottom an obtuse angle to reenforce said container when lying or rolled on its side, said intermediate portions of the body and bottom being disposed in contact with each other and inclined downward and outward to said double seam, to strongly support said container and contents when it stands erect and to locate said double seam in vertical line with the top closure of the container, so that the top and bottom ends of the container are of the same circumference, for supporting said container for rolling in a straight line when the container is lying on its side.

2. In a shipping container for heavy substances the combination of a cylindrical body, a bottom seamed thereto, a stiffening wire enclosed within the outwardly bent top margin of said body, a detachable cover fitting within the top of the body and partially enclosing the top margin ofsaid body and bent to engage below the wire-enclosing part of the body and having lugs bent inward at intervals against and downward along said body, said bottom being elevated above the bottom margin of the container, the outer portions of the body and bottom being united in a double seam, intermediate portions of the body and bottom being outwardly flared to constitute with said bottom an obtuse angle to reenforce said container when lying or rolled on its side, said intermediate portions of the body and bottom being disposed in contact with each other and inclined downward and outward to said double seam, to strongly support said container and contents when it stands erect and to locate said double seam in vertical line with the top closure of the container, so that the top and bottom ends of the container are of the same circumference, for supporting said container for rolling in a straight line when the container is lying on its side.
